DETECT-A-FIRE Heat Detectors

Transcription

1 DETECT-A-FIRE Heat Detectors DETECT-A-FIRE thermal detectors are detection and release devices used for fire detection systems to activate alarms and actuate extinguishing systems. This rate compensated device combines the best features of both fixed temperature and rateof-rise detectors. Typically specified to 100 above ambient.

These highly reliable devices have been a standard for over 65 years. Thousands of these detectors are in use controlling the release of extinguishants such as clean agents, CO 2, water, or dry chemicals. In some systems the device is used as an ALARM device, to sense overheat or fire and alert personnel. DETECT-A-FIRE detectors have met with wide acceptance because they are designed with RATE COMPENSATION. This provides a unique advantage over both fixed temperature and rate-of-rise types of detectors because only the DETECT-A-FIRE detector accurately senses the surrounding air temperature regardless of the fire growth rate. At precisely the pre-determined danger point, the system is activated. Fixed temperature detectors must be completely heated to alarm temperature and therefore a disastrous lag in time may occur with a fast rate fire. Rate-of-rise devices, on the other hand, are triggered by the rate of increase in ambient temperature and are subject to false alarms caused by harmless, transient thermal gradients such as the rush of warm air from process ovens. The secret of the unit s sensitivity is in the design (Figure 1). The outer shell is made of a rapidly expanding alloy which closely follows changes in surrounding air temperature. The inner struts are made of a slower expanding alloy. Designed to resist thermal energy absorption and sealed inside the shell, the struts follow temperature changes more slowly. A slow rate fire (Figure 2) will heat the shell and struts together. At the set point, the unit will trigger, actuating the alarm or releasing the extinguishant. A transient rush of warm air up to 40/min. may expand the shell, but not enough to trigger the unit. By ignoring transient warm air excursions, the DETECT-A-FIRE detector virtually eliminates false alarms prevalent with rate-of-rise devices. If a fast rate fire (Figure 3) starts, the shell will expand rapidly. The struts will close, actuating the alarm and/or releasing the agent. The faster the fire rate of growth, the sooner the DETECT-A-FIRE detector will react. Figure 1. READY Figure 2. SLOW FIRE Figure 3. FAST FIRE F Effective: May 2014

4 HORIZONTAL DETECT-A-FIRE DETECTOR SPECIFICATIONS Horizontal DETECT-A-FIRE detectors are designed for locations where appearance is a factor. The attractive, functional design lends physical protection of the unit while making it suitable for commercial, industrial, mercantile public buildings, institutions and marine applications in non-hazardous locations (those classified as ordinary under the National Electric Code). Flush mounted units are designed to fit standard 4-inch octagonal electric boxes and surface mounting units are designed to mount directly on ceilings or on 4-inch electrical junction boxes. Canadian Electrical Codes requires mounting only to an electrical junction box.

5 VERTICAL DETECT-A-FIRE DETECTOR SPECIFICATIONS Vertical DETECT-A-FIRE detectors are designed for use in both ordinary or hazardous locations. For ordinary use, they may be mounted to any approved junction box with 7/8 diameter opening by using 1/2-14 NPT mounting nuts. The device may be wired in or out of conduit, depending on local preferences and codes. To facilitate supervision of system wiring, four lead wires are provided on normally open vertical units (that close on temperature rise). Per UL requirements, when mounted in a suitable fitting, instruments are Underwriters Laboratory and Underwriters Laboratory of Canada listed and Factory Mutual approved for hazardous locations.

6 MOUNTING DETECT-A-FIRE detectors are not position sensitive. Horizontal and vertical detectors refer to the most common mounting configuration for that unit. However each type can be mounted either horizontally or vertically depending on the application and installation requirements.

CONSTRUCTION Stainless steel shell sensing element. Cold rolled steel mounting facility. Off- finish. TEMPERATURE SETTING SELECTION Fenwal suggests selecting a DETECT-A-FIRE with a temperature setting a minimum of 100 above the maximum ambient temperature expected. Table 6 shows three categories of fire detection devices and their relative response levels for reaction to three different rateof-rise conditions. Statistics indicate that 97% of all fires fall within these categories.
